Guide for building sandbox applications with ComputeSDK, a unified TypeScript SDK for running untrusted code in sandboxed environments across multiple compute providers (E2B, Daytona, Vercel, Modal, Railway, Namespace, Render). Use this skill when implementing sandboxed code execution, creating isolated development environments, running LLM-generated code safely, building app builders, or integrating dynamic code execution into applications.
Guide for creating and managing Daytona sandboxes using ComputeSDK. Use when building applications that need Daytona development workspace environments for code execution, full-featured dev environments, or isolated coding workspaces.
Guide for creating and managing E2B sandboxes using ComputeSDK. Use when building applications that need E2B Firecracker microVM sandboxes for secure code execution, AI code runners, or isolated development environments on E2B.
Guide for creating and managing Modal sandboxes using ComputeSDK. Use when building applications that need Modal's GPU-accelerated sandbox environments for machine learning workloads, AI inference, or compute-intensive code execution.
Guide for creating and managing Namespace sandboxes using ComputeSDK. Use when building applications that need Namespace cloud container instances with customizable CPU/RAM resources for code execution or isolated development environments.
Guide for creating and managing Render sandboxes using ComputeSDK. Use when building applications that need self-hosted sandbox environments on Render's cloud platform for code execution with zero infrastructure setup.

Self-host sandbox environments on Railway's infrastructure through ComputeSDK's unified API. Railway provides instant deployments with automatic SSL — ideal for self-hosted sandbox environments, persistent services, and containerized development.
Before using Railway as a provider, deploy the ComputeSDK sandbox template to your Railway account (one-time setup):
This deploys a lightweight binary that converts Railway into a sandbox provider.
npm install computesdk
# .env
COMPUTESDK_API_KEY=your_computesdk_api_key
RAILWAY_API_KEY=your_railway_api_key
RAILWAY_PROJECT_ID=your_railway_project_id
RAILWAY_ENVIRONMENT_ID=your_railway_environment_id
Get your ComputeSDK key at https://console.computesdk.com/register
railway.com/project/{PROJECT_ID}/settings?environmentId=={ENVIRONMENT_ID}import { compute } from 'computesdk';
// Auto-detects Railway from environment variables
const sandbox = await compute.sandbox.create();
console.log(`Sandbox: ${sandbox.sandboxId}`);
const result = await sandbox.runCode('print("Hello from Railway!")');
console.log(result.output);
await sandbox.destroy();
For multi-provider setups or when you want to be explicit:
import { compute } from 'computesdk';
compute.setConfig({
computesdkApiKey: process.env.COMPUTESDK_API_KEY,
provider: 'railway',
railway: {
apiToken: process.env.RAILWAY_API_KEY,
projectId: process.env.RAILWAY_PROJECT_ID,
environmentId: process.env.RAILWAY_ENVIRONMENT_ID,
}
});
const sandbox = await compute.sandbox.create();
interface RailwayConfig {
apiToken?: string; // Uses RAILWAY_API_KEY env var if not set
projectId?: string; // Uses RAILWAY_PROJECT_ID env var if not set
environmentId?: string; // Uses RAILWAY_ENVIRONMENT_ID env var if not set
}
ComputeSDK provides the same API across all providers: filesystem operations, shell commands, managed servers, overlays, terminals, and client access.
